TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Nov. 30, 1915.

Application filed August 25, 1915. Serial No. 47,250.

To all whom it may concern:

Be it known that I, CLIo B. YAW, citizen of the United States, andresident of Arlington, in'the county of Hudson, and State ,of NewJersey, have invented certain new and useful Improvements inType-Writing Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly towork sheet feeding means.

The main object of the present invention, generally stated, is toprovide simple, inexpensive and yet highly efficient auxiliary feedingmeans by which a stencil card or like may be fed effectively in acylindrical platen machine in substantially a flat condition, so thatthe cards or work sheets need not be bent with a consequent liability ofmutilating or breaking them as they are being fed through the machine.

A further and important object of my invention is to provide means ofthe character specified which are in the nature of an attachment thatmay be readily applied to or detached from typewriting machines now onthe market, without modifying the structural features of said machines,as they now exist, and without impairing the usefulness of said machinesfor ordinary work in which the work sheets are fed around the platen.

To the above and other ends which will hereinafter appear, my inventionconsists in the features of construction, arrangements of parts andcombinations of devices set forth in the following descriptionand-particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicatecorresponding parts in the different views, Figure 1 is a frontelevation, with parts broken away and parts omitted, of a carriage of aMonarch I tvpewriting machine equipped with the auxiliary feed devicesof my invention. Fig. 2 is a vertical fore and aftsectional view of thesame, the carriage being shown mounted in place in the machine. Fig. 3is a detail vertical fore and aft sectional view with parts broken away,the view showing one of the margin feed devices and some of theassociated parts, and the section being taken on the line mac of Fig. 1and looking in the direction of the arrows-at said line.

Fig. 4 is a detail plan view of one of the margin feed devicesshowndetached. Fig. 5

is a detail perspective view of one form of card feeding mechanismembodying my invention, together with some of the associated parts. Fig.6 is an enlarged detail sectional view taken on the line g 4 of Fig. 3and looking in the direction of the arrow at said line. Fig. 7 is adetail perspective view of a modified form of card feeding attachmentconstructed. in accordance with my invention.

I have shown my invention embodied in the present instance in a Monarchmachine in which the invention may be readily incorporated withoutmodifying the structural features of said machine as they now exist, andwithout renderingthe machine any the lesseffective to perform itsordinary work. It should be understood, however, that the invention maybe embodied in other styles of typewriting machines and that variouschanges may be made to readily effect such embodiment.

In the accompanying drawings I have 7 shown only so much of the Monarchmachme as may be necessary to arrive at an understanding of my presentinvention, 1

parts of the usual equipment of said machine being omitted where it isunnecessary to such understanding. 7

The top plate 1 of the machine supports the usual uprights 2 to whichfixed oppositely grooved guide rails 3 are secured by screws 4. Thesegrooved guide rails receive anti-friction balls or rollers 5 which arealso received in oppositely grooved rails G of a guide bar 7, whichconstitutes part of the carriage of the machine. End plates 8 projectforward from this guide bar and support a. platen shaft 9 on which theusual cylindrical platen 10 is mounted. The usual paper feed mechanismof the machine is employed, the main paper feed rollers 11 and 12,respectively, a paper apron 13, paper table 1st and scale plate 15 beingdiagrammatically shown in Fig. 2 of the drawings. The left-hand platenhead is provided with a line spacing ratchet wheel 16 with which a linespacing pawl 17 cooperates. This pawl is pivoted at 18 to a. supportingarm 19 operated bv a rock shaft controlled by a finger piece 20.

The usual margin feed devices and erasing shelf or plate employed in theMonarch machine are included in the present construction and by means ofwhich the auxiliary feed devices of my present invention may bedetachably mounted in place as will hereinafter more clearly appear. Theusual cross rod 21 is arranged above the platen and is secured at itsends to the end plates 8 of the platen frame and supports the marginfeed devices for adjustment longitudinally of said cross rod and theplaten with which they co-act. This rod also constitutes a support forthe erasing plate designated as a whole by the reference numeral Thisplate is formed with ears 23 which are received in reduced bearingportions of the cross rod and thus support the plate at one end by therod, the forward edge of the erasing plate bearing against the face ofthe platen. The rod 21 is formed with a spline groove 2i (see Fig. (3)which extends throughout the length of the rod.

Each of the usual margin feed devices is formed with a bearing sleeve 25which surrounds the supporting rod 21. Each sleeve co-acts with a springspline member 26 which is received in a spline groove 21 of the rod 21,to hold the associated sleeve and the parts carried thereby againstturning movement 011 the rod 21 but enables the sleeves with the partscarried thereby to be adjusted along the cross or supporting rod. 1-rigid forwardly. extending arm 27 is formed on each sleeve 25 and haspivoted thereto at its forward end an arm 28 which carries an inwardlyprojecting spindle 29 surrounded by a spacing sleeve and supporting amargin feed roller 30. A springpressed plunger 31 co-acts with faces 32or 33 on the end of the associated arm 27 to maintain the margin feedroller in either its operative or inoperative position. Each arm 27 hasa paper finger 3st pivoted thereto at 35, each finger being formed withan ofiiset outwardly projecting arm 36 provided with a yoke 37 which issubstantially U- shaped in cross section. The side members of the yokeare pivoted at 35 to the associated arm 27, said members being connectedby a cross plate 38. An expansion spring 39 is received in an opening inthe arm 27 which carries it and bears at its lower end against the crossplate 38 of the yoke of the associated paper finger 34. The pressure ofeach spring 39 is thus exerted to force the associated paper fingeragainst the platen.

A further detailed description of the paper fingers, margin feed rollersand erasing shelf or plate is deemed unnecessary since they are of theusual construction embodied in the Monarch machine, said paper fingersand margin feed roll construction being of the character disclosed inthe patent to Seib No. 921,745, dated May 18, 1909, and the erasingshelf or plate being substantially of the character represented in thepatent to Nielsen No. 790,652, dated May 23, 1905.

Vhile I have described with considerable detail the margin feedmechanism, it should be understood that this description is primarilyfor the purpose of showing the manner in which the mechanism in questioncooperates with the card feed mechanism in a front-strike typewritingmachine to detachably secure said mechanism in place.

From certain aspects of my invention it is immaterial what character ofmargin feed devices are employed so long as they co-act with theauxiliary feed devices to hold the latter in place and afford adetachment thereof.

One form of the attachment by which the cards or work sheets may beeffectively fed in the machine is disclosed in Fig. 5, from which itwill be seen that the attachment or device in question comprises asupporting bar, member or plate .0. This supporting member is formedwith hearing portions 41 apertured to receive a bearing spindle -12which forms a support for a two-part hollow rock shaft 13% The innerends of the hollow shaft are united by a joint comprising feathers orlugs 45 on the inner end of one member of the shaft which are received'in corresponding openings or cutouts 46 in the other member to form aninterlocking engagement between the two to cause them to turn together.There is a slight lost motion between the feathers 45 and the walls ofthe openings 46 in which they are received, as indicated at 47, in orderto afford a slight lost motion between the two members of the shaft andthus pro- Vide for a limited independent rotative movement between them,for purposes which will hereinafter more clearly appear. Each member ofthe rack shaft l3l'-t carries a depending arm 48 fixed thereto in anysuitable manner. Each arm i8 is apertured to receive a spindle 49 whichis in the nature of a headed shouldered screw secured in place by a locknut 50. Each spindle projects inwardly from its supporting arm 48 andcarries an auxiliary or card feed roller 51, located at or near theprinting line and adapted to cooperate with a side edge portion of acard or like work sheet, indicated as a whole by the letter A. Each arm48 is extended rearwardly above the supporting bar 40 and beyond themember of the rock shaft to which it is attached, as indicated at 52. Aleaf spring 53 bears at its free end upwardly against each of therearwardly extending portions 52 of the arms 48 causing the auxiliaryfeed rollers 51 to bear against the platen, or the card interposedbetween the feed rollers and the platen. The outer ends of the springs53 are secured-at 54 to 13 the supporting member 40. It will beunderstood that each of the springs 53 acts individually on itsassociated feed roller 51, this individual pressure of each feed rollerby its spring against the card being afforded by the lost motion betweenthe two members of the rock shaft 43-Ai. The purpose of this is toenable each feed roller 51 to exert its spring pressure against the cardindependently of the other in order to effectively co-act with and feedthe card at one side even though the roller at the other side of thecard be slightly displaced forwardly i from the platen by reason of anyinequality or unevenness in the card. In this manner an effectiveengagement is at all times maintained between the feed rollers 51 andthe card while the latter is engaged by the feed rollers. 5

One of the arms 48 is provided with an' upwardly extending member 55which terminates in a finger piece 56. By moving the latter rearwardlyagainst the pressure of the associated spring 53, the feed roller 51carried by said arm is moved forwardly away from the platen or worksheet and the member 43 of the two-part rock shaft is turned. When thelimit of independent movement between the-two members of the shaft isreached the member a l will be turned, thus releasing the other feedroller 51 from operative engagement with the card.

The supporting member which carries the auxiliary feed rollers isdetachably secured inplace in operative position in the followingmanner: From an inspection of Figs. 2 and 5 it will be seen that thesupportthis end of the member is seated on ing member is formed withdepressions or recesses 57 which constitute bearing seats which, in thepresent instance, cooperate with the sleeves 25 of the margin feeddevices to support the member 40 and. the parts carried thereby on thecross'rod 21. The ends or terminal portions 58 of the supporting member40 are adapted to be received under the connecting members or plate 38of the paper fingers, as illustrated in Fig. 3, and to be pressed by thespring 39 against the erasing plate 22 and on the cross rod 21 or thesleeves 25 carried;- thereby, and thus clamp and secure the supportingmember 40 in operative position.

In attaching the memlier 40 to the'a nachine, one end 58 thereofisEfirst introduced into position. between the spring pressed plate 38of the associated paper finger and the erasing shelf. The seat 57;, atthis end of the member 40 will bear :it this time the sleeve 25 of theassociated paper against The other margin feed device will finger. thenporting rod until its spring pressed plate 38 extends over the oppositeend 58 of the supporting member Miami the seat 57 at the as be adjustedinwardly along the sup-- sociated sleeve 25, and the member 40 will thenbe held firmly in position. When thus positioned the support 40,together with the parts carried thereby, are effectively supported inoperative position ready to receive a card or like work sheet and tocooperate with the platen as the latter is line spaced to effectivelyfeed the card while the latter is maintained in a substantially fiatcondition in front of the platen, as indicated in Figs. 1 and 5.

In order to remove merely necessary to effect an placement of thesleeves 25, and the parts which are carried thereby, away from eachother when the member 4:0 will be released and may be removed from themachine.

The construction disclosed in Fig. 7 is similar to that disclosed in thepreceding figures except that the parts have been simplified. Thus, inthe modified form of construction the supporting member 59 is struck upfrom a single piece of sheet metal formed with supporting ears or hooks60 which constitute seats to engage the sleeves 25 on the margin feeddevices. Ears 61 are likewise formed on the supporting member to receivethe spindle 62 which supports the two-part the attachment it is outwarddisrock shaft 63, 6%. The abutting ends of these members of the shaftare cut-out, as at :65, to provide an interlocking engagement betweenthe two members which causes one to turn with the other, a slight lostmotion being provided, as indicated at (36, to alford a limitedindependent turning movement between the two members of the shaft. A

single spring 67 is secured by screws (38 to and secured in position inthe same manner as the previously described attachment and cooperateswith the platen in the same manner to effect a feed of the cards.

When I refer herein to a card I use that term in a broad sensetodesignate more particularly a work sheet such as a stencil card or sheetof the character shown, cards such as are used for card index systems,envelops or any other work sheet which by reason of its thickness orconstruction renders it dcsirable that it shall be maintainedsubstantially in a flat condition while it is being fed through themachine. It should be understood. however, that the term is notnecessarily restricted to a card of the character specified and thatfrom certain aspects of the invention the mechanism may be employed tofeed the work sheets in any available manner and may be employed inconnection with work sheets of any suitable character.

Various changes may be made without departing from the spirit and scopeof my invention.
